| Source measurement | On 17 March 1969, the first SA 315B, powered by an Artouste IIB engine, undertook its maiden flight . On 30 September 1970, the type received its airworthiness certificate , and it was introduced to operational service in July 1971. Due to its favourable high altitude performance, the Lama quickly became popular with operators worldwide, often being deployed within mountainous environments. As with the Alouette series, the type can be fitted for various roles, such as light passenger transport, agricultural tasks, oil-and-gas exploration, aerial firefighting, and other specialised duties. The military variants of the Lama include liaison, observation, photography, air/sea rescue, transport and ambulance duties. The SA315B is particularly suited to mountainous areas due to its performance and can carry underslung loads of up to 1000 kg (2,205 lb). By December 1976, 191 Lamas had been ordered by 68 operators.[source]Aérospatiale SA 315B Lama · Design and development; only the objects and conditions stated in this passage During 1969, a series of early demonstration flights involving the SA 315B were performed in the Himalayas; during one such flight, a single rotorcraft carrying a crew of two and 120 kg of fuel landed and then took off at what was then the highest altitude to be recorded, 7,500 m (24,605 ft). On 21 June 1972, a Lama with a single pilot ( Jean Boulet ) aboard established a helicopter absolute altitude record of 12,442 m (40,814 ft), a record which still stands as of June 2022. During the same flight, the Lama's engine flamed out at the peak altitude of the flight, which led to an inadvertent record being set for the longest ever autorotation after which the rotorcraft was brought to a safe unpowered landing. Days before, the same pilot and aircraft had set a similar record at a higher weight.[source]Aérospatiale SA 315B Lama · Operational history; only the objects and conditions stated in this passage Derived from the SE 3150, it was designed for high altitude operations using a 650 kW (870 hp) Turbomeca Astazou IIIB turboshaft, derated to 410 kW (550shp). This derivative still holds the absolute altitude record for all types of helicopters since 1972: 12,442 m.[source]Aérospatiale SA 315B Lama · Variants; only the objects and conditions stated in this passage Modified armed combat variant. Changes include composite armouring, toughened glass, and gun sights . Armaments include two jettisonable weapons pods, each of which contains a single 12.7-mm machine gun and up to three 70-mm rockets.[source]Aérospatiale SA 315B Lama · Variants; only the objects and conditions stated in this passage Modernised Indian variant, fitted with the Turbomeca TM333-2M2 for high altitudes operations. Speed is increased to 210 km/h (130 mph) and range is increased to 640 km (400 mi). It has a payload capacity of 90 kg (200 lb) at 6 km (20,000 ft)-altitude and an endurance of 3.5 hours. The engine is fitted with a FADEC system for engine control and an Electronic Backup Control Box (EBCB) system. Additional features include modern cockpit instruments, such as electric-powered artificial horizon, directional gyro, flight monitoring system, cockpit voice recorder, as well as a master flasher warning system. First flight in January 2003. On 2 November, 2004 the helicopter set a world record of highest landing record at 7,070 meters in Himalayas. 10 order by Indian Air Force in 2006 and 20 ordered by Indian Army in 2013.
